About Catwoman

Selina Kyle, also known as Catwoman, is a fictional character portrayed by Michelle Pfeiffer in Tim Burton's 1992 superhero film Batman Returns. Based on the DC Comics character of the same name, this version of Selina is initially depicted as a meek secretary and assistant of wealthy industrialist Max Shreck, who pushes her out of a window when she uncovers his corruption. Selina survives the fall and swears revenge against Shreck as Catwoman, which brings her into conflict with Batman. She forms an alliance with the Penguin to destroy Batman while beginning to date Bruce Wayne, unaware that he is Batman's alter ego. After discovering each other's secret identities, Selina ultimately rejects Bruce's plea to abandon her vengeance and kills Shreck before vanishing into the night.
